Error Messages

CAUTION

Exposing the analyzer to high levels of input power over a prolonged
time period can damage the circuitry.

When operating remotely, the status bit should be monitored for this
condition to avoid incorrect measurement results.

PARAMETER ERROR: _ _ _

The specified parameter is not

recognized by the spectrum analyzer. See the appropriate
programming command description to determine the correct
parameters. (U)

Password required

Indicates that the service function cannot be

accessed without the password. (U)

Power-up selftest failed Boot ROM checksum:

Indicates a

test of the bootrom produced a checksum error. (H)

Power-up selftest failed RAM error:

Indicates a test of

RAM produced an error. (H)

Power-up selftest failed Checksum:

Indicates a test of the

instrument ROM produced a checksum error. (H)

Require 1 signal > PEAK EXCURSION above PEAK

THRESHOLD

Indicates that the N dB PTS routine cannot locate a

signal that is high enough to measure. The signal must be greater
than the peak excursion above the threshold level to measure. (U)

Require 3 signals > PEAK EXCURSION above PEAK

THRESHOLD

Indicates that the % AM routine cannot locate three

signals that are high enough to measure. The signals must be
greater than the peak excursion above the threshold level to
measure. (U)

Require 4 signals > PEAK EXCURSION above PEAK

THRESHOLD

Indicates that the TOI routine cannot locate four signals

that are high enough to measure. The signals must be greater than
the peak excursion above the threshold level to measure. (U)

Required Option Not Installed

Indicates that the function

selected requires optional hardware that is not currently available.
(U)

RF LO Unlocked

Indicates that the local oscillator within the

instrument’s RF assembly is unlocked. (H)
